If you consider yourself a minimalist when it comes to clothing, we'd assume COS is a top contender when updating your wardrobe. While its pieces don’t chase every fleeting micro-trend, it doesn’t mean the brand’s line-up is lacklustre. In fact, it's a treasure trove of capsule wardrobe staples that are especially reliable and incredibly stylish - pieces that slot seamlessly into any clothing rotation. It's no wonder, then, that the Swedish brand has entered the top 10 of the Lyst Index, the global search platform's quarterly list of the hottest brands in the world of fashion.
As fans will already know, COS is a one-stop shop for both quality basics and more directional pieces that look far more expensive than their price tags suggest. Its dress selection is perfect for those who don’t usually gravitate toward dresses, offering elegant, minimal styles that really take the fuss out of summer dressing. Meanwhile, its trouser lineup is just as versatile, perfect for formal occasions but equally capable of creating that cool, off-duty-model vibe when paired with a baby tee. Hence why I spend an unhealthy amount of time refreshing the new in section; and if you love good-quality staples, I’m guessing you do, too.

For this season, the high street brand has continued to deliver on key wardrobe staples, perfect for the balmy months. Its summer 2025 collection boasts quite the selection of impeccably crafted T-shirts, sophisticated yet flowing summer dresses and of course, refined tailoring – this time in linen. Its Holiday Edit is just as good, if not better. We're talking simple yet striking bikinis, sculpting one pieces and cool crisp shirts and trousers that will form the foundations of your destination wardrobe.
As always, tailored favourites continue to be at the forefront of the new in section, from pencil skirts to waistcoats (they have now released a brand new colour of the cult favourite knitted cotton waistcoat) as well as everything in between. Shop our favourite pieces below, before they sell out.
